A study in the journal JAMA Dermatology revealed that nearly one in four men who shave their pubic regions (also known as manscaping) end up injuring themselves.

In an online survey of 7,500 adults, Dr. Benjamin Breyer — associate professor of urology, epidemiology and biostatistics at the University of California, San Francisco — found that 67% of men groom their pubic hair. Of those, 24% injure themselves.

What are the most common manscpaing injuries?

Unsurprisingly, cuts were the most common injury, as 61% of manscapers nicked themselves with a blade. Approximately 23% suffered burns caused by shaving too closely, or stinging chemical products. An additional 12% experienced rashes that can sometimes happen if a person doesn’t use shaving cream, shaves too aggressively or shaves with dull or dirty blades.

A majority of these injuries occurred on the scrotum (67% to be exact). Nearly 35% occurred on the penis shaft itself and 29% occurred on the pubis, the pelvic mound just above the penis.

Luckily, only 1% of the injuries required medical attention.

How can men avoid manscaping injuries?

Dr. Breyer believes pubic grooming has become more popular because of the regular appearance of shortened pubic hair in mainstream porn, but the increased interest in men’s grooming overall undoubtedly plays a role, too. After all, some guys just feel cleaner with a trim, enjoy the sensation of freshly shorn genitals or prefer the appearance of clipped pubes.

Shave in the direction of the hair (not against it), and if you cut yourself, use warm water, soap, rubbing alcohol and toilet paper to stop the bleeding and clean the area, otherwise the bacteria down there can potentially cause an infection.

And when you’re done, treat your entire groin to some moisturizer to help keep your equipment from getting irritated or itchy.
